Title: Information recording device consisting of high-polymer ferroelectric material
Inventor: SHIBATA ISAMU
IPC: B41M5/26
Filed: 1988-07-06
Abstract: PURPOSE:To increase a writing speed by binarizing the change in the current of a power source which impresses a voltage between the electrodes on both surfaces of a vinylidene polymer, i.e. the change in the polarization inversion current thereof, at the time of recording, then comparing the same with a recording information signal and detecting the change. CONSTITUTION:The voltage below the anti-electric field is impressed between the electrodes 2 and 3 on both surfaces of the vinylidene polymer 1 at the time of recording and said surfaces are irradiated with laser light 7 subjected to on-off modulation according to recording information from an optical pickup 6. The polarization of the part irradiated with the laser light 7 where normal recording is executed is inverted in said part and is detected as the polarization inversion current of the current change of the power source 5. However, such polarization inversion is abnormal and insufficient when the recording state is abnormal and, therefore, said current is not detected as the polarization inversion current. Such change in the current is compared with the recording information signal and is detected after the binarization. Whether there is the abnormality in the recording state or not is thus simultaneously checked. The writing speed is increased in this way.

Filed: 1993-07-08
Abstract: PURPOSE:To obtain small-sized, simple structure with high performance and connect an antenna selectively to a transmitter or receiver by combining a switch device, a receiving filter, and an impedance adjusting element. CONSTITUTION:When a switch 200 is OFF, a PIN diode D1 turns OFF, the impedance viewed from an antenna terminal 10 to a transmission terminal 9 becomes almost infinitely large, and the signal at the terminal 10 is supplied to the receiver 102 through a BPF 8. When the switch 200 is ON, on the other hand, the D1 turns ON and its impedance becomes nearly zero. An air-core coil 6 is connected to a connection point P1 and the admittance viewed from the terminal 10 to the BPF 8 is almost zero at a transmission frequency. A reception terminal 11 is therefore electrically disconnected from the terminal 10 at the transmission frequency and the D1 turns ON, thereby connecting the terminal 10 to a transmitter 101.

Title: Electric field type human body detector
Inventor: TAKADA YUUJI
IPC: G08B13/26
Filed: 1980-11-28
Abstract: PURPOSE:To eliminate the possibility of false announcing occurring due to such  as higher harmonic noises generated synchronously with an electric power source by holding an electric power source frequency at non-integer times with a frequency conversion circuit thereby obtaining a detection signal. CONSTITUTION:A frequency conversion circuit 1a has a multiplying circuit, generates the signal of the frequency non-integer times the electric power source frequency and supplies the same to an oscillator 1b. The oscillator 1b oscillates at the output frequency of the circuit 1a and applies the output thereof as a detection signal to an exciting line 2. In this way, the frequency of the detection signal is fixed at non-integer times of the power source frequency, whereby the detection signal is positioned approximately at the center of the frequency of the higher harmonic noise of the power source, and a beat is set so relatively high frequency as to be blocked with a BPF 6; therefore, the possibility of causing malfunction of an announcing circuit by the beat in accordance with the higher harmonic noises is eliminated.

Abstract: PROBLEM TO BE SOLVED: To prevent sewage from falling in an anaerobic state by installing a hollow- yarn membrane module of which the end part in the flowing-out side is sealed in a sewage pipe and supplying oxygen or air from the end part in the flowing-in side of the hollow-yarn membranes. SOLUTION: Sewage is pumped up by an pumping up pump 2 installed in a sewage conduit 1, foreign substances contained in the sewage are removed by an auto-strainer 3, and the resultant sewage is supplied to a hollow-yarn membrane module 5 through a flow rate adjusting apparatus 4. On the other hand, air is compressed by an air compressor 6 and sent to an oxygen concentrating apparatus 7 to heighten the oxygen concentration and stored in an oxygen tank 8. The obtained oxygen is supplied to the end part in the flowing-in side of the hollow-yarn membrane module 5, of which the flowing-out side is sealed, in a pipe 10 through the pressure regulating apparatus 9. Consequently, oxygen flows into the hollow-yarn membranes from the end part of the flowing-in side of the hollow-yarn membrane module 5. Since the flowing-out side is sealed, oxygen is supplied to the sewage from the fine pores of the surfaces of the hollow-yarn membranes. As a result, oxygen is efficiently and sufficiently dissolved in the sewage and hydrogen sulfide evolution can efficiently be prevented.
